Resonant Wireless Power Transfer Workshop

About: Hi! I'm Staci =) If you're looking for creative hacking and making of all sorts of things, you've come to the right place. High speed board designer, power electronics practitioner, and system architect...

In this presentation we're going to use the $7 ZVS drivers made for induction heating to provide wireless power for LEDs in your fish tank, toy cars that are powered from under the track, charging your smart watch with a loop in the steering wheel of your car and another in your watch band (good coupling :) )...Etc.


First draft of slides so go easy on me...

Step 1: Introduction to Wireless Power

Step 2: Mutual Inductance and Resonance

Step 3: DC Source

Step 4: Oscillator

Step 5: Oscillator Continuted...

Step 6: Oscillator Waveforms of Interest.

Step 7: TX Loop

Step 8: TX Loop Continued.

Step 9: TX Loop Continued.

Step 10: A Little on Resonance...

Step 11: A Little More on Resonance.

Step 12: Our TX Loop Resonance. 8A RMS!?!? WOW.

Step 13: Moving on to RX Side

Step 14: Multiply by N^2 Huh?

The advanced workshop will go over error of the approximations used in this workshop as compared to FEM.

Step 15: RX Coil Detail

Step 16: Resonance Calculation

Step 17: Rectifiers

Step 18: Future Slides Todo

Step 19: Ack...

Step 20:
